9 Claims.

This invention relates to improvements in road markin machines and itsobject is to provide for machines of this character an adjustable brushof simple and novel construction which is capable of putting markingfluid on desired surfaces in lines of different widths with clearlydefined sharp edges regardless of the smoothness of the surfaces towhich the fluid is applied.

My invention also relates to certain details of construction which willbe described hereinafter.

I will describe in the following specification a device which is madeaccording to and embodies my invention and will point out its novelfeatures in the appended claims.

Referring to the drawings:

Figure 1 is a plan view, and

Fig. 2 is a side elevation of a road marking machine which is providedwith my novel adjustable brush and the support therefor;

Fig. 3 is a plan view on a larger scale of the brush which is shown inthe preceding figures;

Fig. 4 is a sectional elevation of the brush shown in Fig. 3, thesection being taken on the line 4-4 of the latter figure;

Fig. 5 is an inverted plan view of the brush shown in Figs. 3 and 4;

Fig. 6 is a perspective view of one of the elements of the brush;

Fig. 7 is a sectional front elevation of a detail of constructionshowing a novel arrangement of supporting the brush on the body of themarker.

Referring to Figs. 1 and 2, I designates the chassis of a marker whichis supported on two wheels I I, l near the rear sides of the apparatusand a central front wheel l2. I3 is an adjustable sight for enabling theoperator to follow a guide line. I4 is a main tank for the markingfluid. When the apparatus is constructed as shown to make two parallellines, this main tank may be divided longitudinally to form twocompartments. is an auxiliary tank in front of the main tank for holdingliquid in which the brushes may be submerged when not in use. l6, l6 aremetallic strips which run upward from the chassis l0 obliquely along thesides of the main tank l4 and above it. A transverse handle barinterconnects the upper ends of the straps l6. l8, 3 are verticalmetallic straps extending downwardly from the oblique straps |6, It, toand below the chassis ID to form a support for a transverse shaft I9.

20 is a sleeve rotatably surrounding the shaft I9. Brush supporting arms2|, 2| are aifixed to is a lever keyed to the sleeve 20 and connected bya rod 23 with an adjusting handle 24 pivoted to one of the rods I6 withits rearend situated near the handle bar By means of this arrangementthe brush supporting arms 2 I, 2 I, may

. The latter extend up to a position near the handle bar IT.

The parts thus briefly described are common to road markers and form nopart of the present invention.

3!] is a rigid rectangular frame fromopposite sides of which hooks 3|extend upwardly (Fig. 7). These hooks fit loosely in notches 28 in thebrush supporting arm 2| and are retained in these notches by pivotturn-buttons 29 or similar devices. 32 and 33 designate longitudinallydisposed brush supports, transversely adjustable in the frame 30. Therear end of each of these brush supports is shaped to form a tenon whichslide in a groove 34 in the frame 39 (Figs. 3 and 4). 35 is a right andleft hand threaded adjusting screw rotatively mounted transversely inthe frame 39. 36 designates a winged nut affixed to to the screw forturning it. The screw passes through threaded holes in the brushsupports 32, 33.

The brush elements comprise longitudinal parts 40 and which arepreferably of equal length. Transverse parts 4| and 5| extend inwardlyfrom the longitudinal parts near the rear ends thereof but in suchrelative positions that they overlap each other. 42 and 52 arereinforcements for the longitudinal portions of the brush elements andserve to keep them from spreading. These brush elements are affixed tothe brush supports 32, 33 by screws 43, 53.

In operation, the brushes are lowered to the surface in the usual way,the fluid supply valve is opened and the apparatus moved in thedirection of the arrows A in Figs. 3 and 5.

In operation .the brushes are lowered to the surface in the usual way,the fluid supply valve is opened and the apparatus moved in thedirection of the arrows A in Figs. 3 and 5. The pool of liquid formedbetween the brush elements will be evenly distributed upon the surfacetraversed by the brush elements. Because of the loose conthis sleeve andextend rearwardly therefrom. 22 55 nections between the frame 30 and thebrush supporting arms 2|, the device will accommodate itself to majorinequalities in the surface traversed and the brush elements themselvesremain in contact with the surface as the resilience of the bristles orwires of which the brushes are made cause them to reach into minorinequalities or indentations in the surface. The longitudinal members ofthe brush elements cause the edges of the mark made to be sharp andclearly defined and this effect is enhanced by the reinforcements 42, 52which keep the brushes from spreading laterally. Worn brushes may bereadily replaced with new ones.

To adjust the width of the mark made the screw 35 is turned by thewingnut 36 to vary the space between the longitudinal members 4!] and 50of the brush elements. To facilitate such adjustment, an indicating mark31 is made on one of the brush supports and a graduated scale 38 made onan adjacent part of the frame at.

Various structural modifications may be made within the spirit and scopeof this invention and I intend no limitations other than those imposedby the appended claims.

What I claim is:

l. A road marker brush comprising a pair of brush elements having spacedparallel'straight parts, and a transverse part rigidly connected witheach of said spaced parts projecting inwardly therefrom.

2. A road marker brush comprising a pair of brush elements having spacedparallel straight parts, and a transverse part rigidly connected witheach of said spaced parts projecting inwardly from intermediate portionsthereof into overlapping relation.

3. A road marker brush comprising a pair of brush elements having spacedparallel straight parts, a rigid reenforcement arranged to retain saidstraight parts laterally, and a transverse part rigidly connected witheach of said spaced parts projecting inwardly from intermediate portionsthereof into overlapping relation.

4. An adjustable road marker brush comprising a pair of brush elementshaving spaced parallel straight parts, a transverse part rigidlyconnected with each of said spaced parts projecting inwardly fromintermediate portions thereof into overlapping relation, and means foradjusting the relative transverse positions of said brush eleents.

5. An adjustable road marker brush comprising a pair of brush elementshaving spaced parallel straight parts, a transverse part rigidlyconnected with each of said spaced parts projecting inwardly fromintermediate portions thereof into overlapping relation, and means forsimultaneously moving said brush elements toward or away from each otherto vary the space between said parallel parts.

6. An adjustable road marker brush comprising a rigid frame, a pair ofbrush holders transversely slidable in said frame, a brush elementaffixed to each of said brush holders, each of said elements having astraight part affixed to one of the brush holders, a transverse partrigidly connected to said straight part projecting inwardly fromintermediate portions thereof into over lapping relation with thetransverse part projecting from the straight part of the other brushelement, and means for adjusting the positions of the brush holders inthe frame.
